sky2: fix transmit state on resume 

This should fix http://bugzilla.kernel.org/show_bug.cgi?id=8667

After resume, driver has reset the chip so the current state
of transmit checksum offload state machine and DMA state machine
will be undefined.

The fix is to set the state so that first Tx will set MSS and offset
values.
